Singer and actress Miley Cyrus has revealed that she suffers from the heart condition tachycardia.
In her autobiography 'Miley Cyrus: Miles To Go', the young star wrote: "The type of tachycardia I have isn’t dangerous."
"It won’t hurt me, but it does bother me. There is never a time onstage when I’m not thinking about my heart."
The singer said that the condition causes her resting heart rate to beat faster than it should.
